Abstract. By means of consistent
solution of motion equation for magnetization the dissipation
for magnetostatic surface waves (MSSW) propagating on in-plane magnetized
ferrite plate is considered. The complex character of wave
number caused by the dissipation is revealed. The approximation of small
value dissipation is investigated. For the case of typical material and excitation frequency
parameters appreciation of its employment is found. In this
approximation the dispersion relations for real and imaginary parts of wave
number are found.
Key words: ferrite, magnetostatic
waves, dissipation.
